Vanagon – heckklappen-aufsteller (rear hatch propped open gizmo)

I had a go at making one of those gizmos that allows you to have the rear hatch open a crack, but still locked. I used the plans on this page, specifically this pdf. As shown on that same page, you can make an easier version from a turnbuckle. My attempt is pretty crude, but it works. The D shaped hole goes over the post on the van body, and round hole engages the latch on the hatch.
